Yes I did, I’ve drilled through the rivets en was possible to pull the exhaust apart.
the next thing I did was to grind the DB-killer out (this one is welded tot the exhaust). when your careful enough you can only remove the weld en don’t damage the outer parts of the exhaust.

the one problem I had was the inner wool… once the exhaust is dissected you won’t be able to put the wool back.

the sound the exhaust makes isn’t that loud (you still have a major mid damper what will filter enough noise out).

the other thing you can do is to buy a ackropovic from a KTM duk 390, they have the same engine and frame.

I’ve personally opted for the Akra. Not really louder but it gives a deeper tone to the bike. It’s still a bit muffled full throttle. I’m also gonna go for the cat delete to free up the sound a bit more without going no db-killer.

IMO not exactly worth the 600€ asked for the Akra but the built quality is very gweeed. I’m also thinking resale value for the bike when the day arrives. I can’t speak for the other brands though, I almost went to the LV-10 from Leo Vince but the racy only use put me off.

I work for a dealer southern california and we tested bunch of diferent pipes and they dont make more power only noise. I have done testing on my 2017 duke390 and my 401 for the past 7 months and cutting out the db killer only makes it stupid loud. The best and most safe and reliable set up is the competion werks mid pip with the coober ecu and leave the db kill in or you will kill bottom end power Its all plug and play. Your bike will run much cooler smoother and pic up some power.
